The old man Mozhigen arrived as promised. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

The old man was accompanied by a large flock of sheep and nine horses.

The sheep flock is to provide on-site fresh milk to the soldiers and civilians of Changsheng Fort according to the agreement.

The nine horses are called a nine according to the customs of the grassland, and the old man said that it was Qiqige's dowry, and the white horse was specially given to Sun Yi.

This is a bribery ballot in the open, but the whole Ironwood battalion can't refuse.

Moreover, the Ironwood Battalion was in dire need of large livestock. The consumption of one horse is as high as six soldiers, so on the way to Langshan River, Yang Ritian left some mules with rough skin and thick flesh that were easy to feed but could not give off cubs, many delicate horses were abandoned, and there were no cattle.

After greeting the old man, Sun Tong put forward a constructive idea.

Sun Yi proposed that Changsheng Township was busy cultivating the land, and the nomads of Hesheng simply drove the cattle down, and Changsheng Township rented Hesheng's cattle to cultivate the land, and the rent was paid with future grain.

Sun Yi's later generations of Mongolian buddies have a saying, "The family has a lot of wealth, but the hairy ones don't count." It is said that nomadic herders have herds of cattle and sheep, which can easily be converted into millions of yuan, but they live a poor life. It is because grazing is really a large-investment, long-term, risky industry, there is no cash inflow in the nomadic process, and there is no non-stop investment, and a few years of uninterrupted hard work can make you return to the pre-liberation period overnight as long as a natural disaster.

As long as the people of Hesheng drive the cattle down and graze and plow, they can have income, and the people of Changsheng get more land, a win-win situation. Sun Yi was excited about his genius idea, waiting for the old man's praise.

Morrigan didn't speak.

Qiqige pulled the corner of Sun Yi's clothes and shook his head desperately, "Brother Yi, Hesheng's cattle can't plow the land. ”

Sun Yi was stunned, the cow actually couldn't plow the land?

Mo Rigen opened his mouth, and the cattle had to plough the land, and there were three passes.

The first level is that when the cow is small, it must be fanned first, otherwise the cow will have too much temper.

The second level is that when the cow is one year old, it must wear the cow's nose so that the cow can be honestly led by others.

The third level is when the ox grows to the point where it can plow the land, it is necessary to ask a special master to tame it, one to plough the ox to go straight, and the other to plough the ox to the head of the ground will turn around.

The cattle of Wakatsu are all beef cattle and dairy cows, and they have long missed the time to become ploughing cattle.

Sun Yi smiled awkwardly, "It seems that not only do I not distinguish between the five grains, but also the six animals." ”

"Riddell's idea is a good idea, I'll go back and have someone try it on a horse," Morrigan explained. ”

Sun Yi raised his eyebrows, unable to believe it, "Horses can also plow the land?" ”

The old man Mo Rigen smiled generously, "Hesheng also has land, and it has been horse farming for the past two years. ”

Sun Yi shook his head, "Forget it, let Changsheng Township negotiate directly with you, I don't care if you take sheep to plow the land." I'd better be honest and do something I'm sure of. ”

For example, Sun Yi is very sure of the high-efficiency shortening machine, and it has been successfully trial-produced.

To be honest, the craftsmen were able to come up with a prototype so quickly, and Sun Yi didn't expect it at all.

After returning from Hesheng, Sun Yi explained to the craftsman the task of developing a ghee machine. I didn't expect a big man in the hall to be called a doctor, no, now called a doctor, blurted out, "This thing can be done with a fan, it's very easy!" ”

A fan cart is a type of agricultural tool that is used to raise grains. After the crops have been harvested and threshed, the bran, the broken rice stalks and the grains are separated by a fan.

Hand-raised grain is called Yangchang, in which the grains are thrown into the air when there is a strong wind, the chaff is blown away by the wind, and the grains fall to the ground, which is slow and laborious.

Ancient Chinese craftsmen invented the fan car, also known as the "fan car", in the Han Dynasty. The grains poured into the hopper of the fan cart are constantly subjected to the strong air currents generated by the rotation of the fan wheels. The wind blows the chaff to the ground through a hole at the end of the fan, and the kernels slide down into the container that sits underneath the fan.

The fan wheel consists of a wooden shaft and six to eight blades fixed to it, which is mounted in a circular cabinet and can be operated by a small crank crank or by a foot pedal attached to the crank, so that the operator can free up his hands to do other tasks at the same time.

"Wujing General Essentials" and "Tiangong Kaiwu" all have records of fan cars, and "Tiangong Kaiwu" is also equipped with illustrations of fan cars. The fan car comprehensively uses the principles of fluid mechanics, inertia, lever and so on, and is a "high-tech" product in the history of agricultural tools in the world, which has been used in China until the 1970s.

Fan carts were brought to Europe between 1700 and 1720 by Dutch sailors. Before that, the West mainly used the method of raising the valley and using a dustpan to make the grain. They were amazed to find that the fan from China could process 17 barrels of grain (one barrel is equivalent to about 1.6 cubic meters) a day. European engineers worked hard to improve the design to suit the size of the European kernel and to combine it with machine threshing.

The craftsmen of the old camp in the woods have already made two ready-made fan carts. According to the customs of the Ming Dynasty, everything that could be turned was called a car, and it was named "cream car".

Sun Yi took Mo Rigen to the prototype of the "cream car".

This machine is half a person tall. The original grain inlet was changed to a milk inlet, and the fresh milk directly entered the fan wheel box from the milk inlet, and was thrown to the height of the original air outlet on the side of the box under the hitting and stirring of the fan wheel. Here, the fresh milk enters the milk channel, is filtered by gravity by a small piece of reed mat and returns to the fan box. Repeated beatings and filtering will gradually deposit the sticky cream on the reed mat strainer. As long as the reed mat filter is replaced, the whole process can be carried out continuously.

Kikige excitedly demonstrated to Morrigan.

She poured a bucket of freshly milked goat's milk into the "cream cart" on tiptoe, and when her foot stepped on the pedal, the "cream cart" whirred.

It turned out that the ghee was beaten with a bucket, and it was counted as a thousand times. The fan wheel of the cream car rotates eight times, and the kung fu fan wheel can turn many times in the blink of an eye.

No one knows if there is still oil in the milk after beating the ghee with a bucket for a thousand times, but now as long as you don't stop, you can know whether the cream is squeezed clean by looking at the reed mat slices.

Mo Rigen smiled,

"Lidel, I originally wanted to exchange fresh milk for some medicine to fight insects, but now I'm afraid I have to change my mind, otherwise the girls won't spare my old bones when I go back."

Sun Yi helped Qiqige add a bucket of milk to the cream cart,

"Uncle Mo Rigen, don't worry about the medicine for fighting insects. When you join the Ironwood Battalion, you won't have to change anything, but I'm going to give everyone a few free insecticides. ”
